Spin Chern phases and persistent spin texture in a quasi 2D SSH model
Hemant K Sharma, Saptarshi Mandal, Kush Saha
We construct a quasi-two-dimensional Su Schrieffer-Heeger model (SSH) like model and uncover a rich set of topological phases with nontrivial spin textures in the presence of compl…
Quantum Otto heat-engine with Kitaev-Heisenberg cluster: Possible roles of frustration, magnons, and duality
Sheikh Moonsun Pervez, Saptarshi Mandal
We study the performance of Kitaev-Heisenberg (KH) clusters as working media realizing a quantum Otto engine (QOE). An external Zeeman field with linear time dependency is used as…
Extended Haldane model -- a modern gateway to topological insulators
Tanay Nag, Saptarshi Mandal
The seminal Haldane model brings up a paradigm beyond the quantum Hall effect to look for a plethora of topological phases in the honeycomb and other lattices. Here we dwell into t…
Deciphering competing interactions of Kitaev-Heisenberg- system in clusters: part II -- dynamics of Majorana fermions
Sheikh Moonsun Pervez, Saptarshi Mandal
We perform a systematic and exact study of Majorana fermion dynamics in the Kitaev-Heisenberg- model in a few finite-size clusters increasing in size up to twelve sites. We empl…
Emergent topological phases in an extended Su-Schrieffer-Heeger model with Rashba spin-orbit interaction, higher order hopping and domain wall
Hemant Kumar Sharma, Arijit Saha, Saptarshi Mandal
We theoretically investigate emergent topological phases in an extended spin-full Su-Schrieffer-Heeger (SSH) model considering Rashba spin-orbit interaction, all possible complex n…
